Since the deformation region involves interaction of electric-thermal-force coupling in electric hot incremental sheet forming, numerical simulation forming process is unusually difficult. Currently, thermal-force method adopted to simulate approximately whole process, and Joule heating effect often ignored. Therefore, especially significant for prediction accuracy process. In this paper, a nov...

Abstract: In this paper, the forming process of a central hub by radial-forward extrusion is analyzed by using the finite element software, ABAQUS. Radial-forward extrusion is used to produce hollow parts that generally feature a central hub with radial protrusions. Effective design factors such as mandrel diameter, die corner radius, die fillet radius, mandrel corner radius, tube wall thick...

during the years after the end of the cold war and parallel to the forming a new practice for the use of force under the title of the humanitarian intervention, different theoretical endeavors have been made to understand the formation of the mentioned interventions. the theoreticians, using constructivism, cosmopolitanism, english school and realism theories, have tried to explain the said phe...

ultrasonic vibration assisted single point incremental forming (uvaspif) process is an attractive and adaptive method in which a sheet metal is gradually and locally formed by a vibrating hemispherical-head tool. the ultrasonic excitation of forming tool reduces the average of vertical component of forming force and spring-back rate of the formed sample. the spring-back phenomenon is one of the...

Electromagnetic forming is a high energy rate forming process. In this process, an electromagnetic Lorentz body force is used for deformation of products. In this article, Electromagnetic forming process was simulated for assembly of parts as an innovative method. In this research work, the effect of important parameters of process such as discharge energy, radius and width of rectangular groov...
